What Are Coffee Roasts?
Roasting is the process of heating green coffee beans to bring out the oils and flavors hidden within them. The roasting process involves carefully applying heat, controlling time, and manipulating the environment to create complex chemical changes in the beans. This process ultimately influences the coffee’s flavour, aroma, body, and acidity.
Roasts can be categorized into four main types: Light, Medium, Medium-Dark, and Dark. Each roast level brings out a unique profile in the coffee, altering its overall taste.
Types of Coffee Roasts
1. Light Roast
Light roasts retain most of the coffee bean’s original characteristics. These roasts are known for bright, acidic flavors with fruity or floral undertones. Light roasts typically have a lighter body, allowing the origin’s natural flavors to shine through. They also have higher acidity compared to darker roasts.
- Appearance: The beans are light brown in color with no surface oil, as they aren’t roasted long enough for oils to break through.
- Best Suited For: If you enjoy delicate flavors with more acidity, a light roast is ideal. They’re perfect for tasting the nuances of single-origin beans from places like Ethiopia or Colombia.
- Brewing Methods: Pour-over, Chemex, or Aeropress to highlight the bean’s subtle flavors.
Popular Variants
- Cinnamon Roast: Light and zesty.
- New England Roast: Slightly more caramelized but still bright.
2. Medium Roast
Medium roasts offer a balance of acidity and body, with flavors that are richer and more complex than light roasts. These roasts often have a hint of sweetness with well-rounded flavors and a medium body. Acidity is toned down while the roast starts to bring out caramel and chocolate notes.
- Appearance: Medium brown beans, with a non-oily surface.
- Best Suited For: If you enjoy balanced flavors with mild acidity and some sweetness, medium roasts are a great choice. They often work well for people who want versatility in their coffee drinks, from black coffee to lattes.
- Brewing Methods: Drip coffee makers, French press, and espresso machines.
Popular Variants
- American Roast: Commonly used in the U.S., offering a smooth, balanced flavour.
- City Roast: Slightly darker, bringing out more caramelized sugars and balanced bitterness.
3. Medium-Dark Roast
As you progress to medium-dark roasts, you’ll notice a shift towards fuller-bodied coffee with deeper flavors. The acidity continues to diminish, while the sweetness from caramelization intensifies. You’ll get roasted, nutty, or spicy notes with a heavier mouthfeel.
- Appearance: Darker brown beans, often with a slight sheen of oil on the surface.
- Best Suited For: Those who enjoy a more robust coffee with a balance of sweetness and bitterness. The flavors are deeper and more complex, making it an excellent choice for those transitioning from light roasts to darker profiles.
- Brewing Methods: Espresso, Moka pot, and French press.
Popular Variants
- Full City Roast: Has a rich body with toasty, bittersweet flavors.
4. Dark Roast
Dark roasts are bold, full-bodied, and intense. The original flavors of the beans are almost entirely overshadowed by the roasting process, resulting in smoky, chocolatey, and sometimes slightly burnt flavors. The body is heavier, with little to no acidity.
- Appearance: Very dark brown, almost black beans, with an oily surface. The oil indicates that the beans have undergone extended roasting.
- Best Suited For: If you love a bold, strong coffee that’s low in acidity with a heavy mouthfeel, dark roasts are your go-to. These roasts tend to be more bitter and are great for milk-based coffee drinks like lattes and cappuccinos.
- Brewing Methods: Espresso machines, Moka pot, and cold brew.
Popular Variants
- French Roast: Dark, smoky, and full-bodied.
- Italian Roast: Very dark with intense flavors, often used for espresso.
How Roasting Affects Coffee Flavor?
Let us understand how roasting plays an important role in shaping the final flavor of coffee:
- Acidity: As the roast level increases, acidity decreases. Light roasts are high in acidity, while dark roasts have minimal acidity.
- Body: Light roasts have a lighter body, whereas dark roasts tend to have a fuller, more robust body. Medium and medium-dark roasts offer a balanced body.
- Aroma: Light roasts often carry fruity, floral aromas, while dark roasts smell smoky and rich. Medium roasts lie in the middle, with aromas of caramel, nuts, or chocolate.
- Flavor: Light roasts are more vibrant and preserve the bean’s origin flavors, while dark roasts develop roasted, bittersweet, and sometimes smoky notes due to the caramelization of sugars.

Frequently Asked Questions
Here are a few Interesting FAQs on types of Coffee Roasts
The key difference lies in the roasting time and temperature. Light roasts are roasted for the shortest time, retaining the bean’s natural flavors, high acidity, and light body. Medium roasts are roasted longer, offering a balance between acidity and sweetness with a fuller body.
Dark roasts are roasted the longest, resulting in bold, bitter, and smoky flavors with low acidity and a heavy body.
Yes, but not in the way many people think. Light roasts generally contain slightly more caffeine by volume than dark roasts, since darker beans expand more and lose mass during roasting.
However, the difference is minimal, and caffeine content largely depends on the amount of coffee you use, rather than the roast.
Medium to dark roasts are typically preferred for espresso because they offer rich, bold flavours with low acidity and a full body. Dark roasts like French or Italian are especially popular for espresso as they create the intense flavours and crema many espresso lovers enjoy.
Yes, but dark roasts tend to be the most popular for cold brew due to their smooth, rich flavours that complement the cold brewing process. However, if you prefer a brighter, fruitier cold brew, a light roast can also be used for a refreshing, acidic finish.
The appearance of the beans provides clues. Light roasts are light brown with a matte surface, as the oils don’t reach the surface. Medium roasts are slightly darker and may have a subtle sheen. Dark roasts are deep brown to black with a shiny, oily surface due to the longer roasting time.
Conclusion
Whether you’re a fan of the bright, floral notes in a light roast or the deep, smoky intensity of a dark roast, understanding the different types of coffee roasts helps you make an informed choice for your brew. By experimenting with different roasting levels, you can discover your ideal coffee experience and elevate your morning ritual.
So next time you’re selecting beans, consider the roast level and how it will enhance your cup of coffee. Happy brewing!
